Motivated by the asteroseismic potential of pulsating low- mass white dwarfs, and stimulated by the discovery of the first variable ELM white dwarf, we have started in the La

For single stars, the minimum mass of a present day white dwarf is around 0.30 − 0.45 M ([2]), because progenitors that would become lower mass white dwarfs have main

Water vapor tends to be high in concentration within the leaf (ideally at 100% relative humidity), so water has a natural tendency to diffuse out of the leaf – and it diffuses
